ZBALING MACHINE.

Applicationfiled March 10, 1920. Serial No. 364,744.

To all whom it may concern:

Be it known that I, IVILLiAM H. MARTIN, a citizenof the United States,residing at Davenport, in the county of Scott and State of Iowa, haveinvented certain new and use ful Improvements in Baling Machines, ofwhich the following is a specification.

My invention has reference to baling machines, such as are used inbaling'paper, rags, and similar material, and it is an improvement on amachine of that class for which Letters Patent of the United States No.1,133,048 were issued to Fred A. Lundahl Mar. 23, 1915. The chiefpurpose thereof is to improve the general construction of the machine,so as to increase the efficiency and operation thereof.

During the baling operation a considerable amount of force is exertedupwardly, through the compressing devices, so that the superstructurewhich carries such devices must be specially designed and constructedfor the work required of it, and bepositively held in place when thecontents of the machine are under compression. One of the features ofthe present invention is a superstructure, or supporting frame for theplunger mechanism, which possesses a combined strength and eifciencyexceeding that of other similar machines.

In the drawings:

Fig. 1 shows the invention in front elevation.

Fig. 2 is a vertical section on the broken line 2-2 of Fig. 1. I

Fig. 3 is a plan view of the supporting frame for the compressingdevices.

Fig. 4 is an end view thereof.

Fig. 5 is a cross-section through the rear wall of the machine.

Fig. 6 is a detail of the upper door locking mechanism.

The device comprises a receptacle, formed of side plates 1, a rear plate2, and a front door 3, hinged to one of the side plates, and providedwith a drop portion 4, hinged to the part 3. The door 3 is held normallyin a closed position by means of a catch 5, pivoted to the front of thedoor and engaging a frame 6, swingingly mounted at one side of the door.The section 4 is held in a closed position by means of a shaft 7,rockingly supported near the upper edge of the door, and provided on itsends with latch-es 8, adapted to engage catches 9 on the side plates 1.At a central point on the shaft 7 is a handle- 10, by means of which thelatches 8 can he released, and which also acts as a weight, to hold saidlatches against accidental release. When the section 4 is opened, the.

downward. movement thereof is limited means of arms 11, pivoted at theirupper ends thereto, and slotted at their lower ends for engagement withpins in the edges of the part 3. When the section 4 is returned to aclosed position the latches 8 will automatically engage. the catches 9,such latches being held in an engaging position by a projection 12 onthe handle 10, hearing against the face of the door.

The machine is provided with a support 2 ing frame, or superstructure,consisting of two pairs of parallel cross-plates 14, united at theirends by plates 15, extended in each direction beyond the side-plates. Inthe endplates 15 are bearings 16 for a shaft 17 on which is fixed apinion 18, in engagement with a rack 19, on one end of which Visaplunger 20. The rack 19 has a rib 21 which has vertical play in anextension 22 of a frame 23, centrally of the frame 14, and accommodatingthe pinion 17. Projected rearwardly and downwardly from the rearcross-plate 14 is a pair of wings 24, spaced so as to pass downwardlyjust within the side plates of the receptacle, to which they arepivotally attached, as at a. By this means the supporting frame ispermitted to tip rea-rwardl'y, carrying with it the compression devices,as shown in Fig. 2. Extended forwardly in line with the wings 24 arelips 25, which project downwardly just within the side walls of thereceptacle when the parts are in an operative position, and assistinholding the superstructure from side play. The extensions 24 and lips 25also assist in maintainingthe walls of the receptacle in. properrectangular position with relation to each other.

The forward edge of the superstructure is provided with a pair ofopenings 26, adapted to receive latches 27, pivoted to the side plates 2near the upper edges thereof, and holding the superstructure from upwardmovement when the contents of the machine are under compression. When itis desired to clear the top of the machine, the latches 27 are swungforwardly, as shown in Fig. 2 of the drawings. The latches 27 andlatches 8 combine to keep the forward edges of the side walls 2 of thereceptacle from spreading when the machine is under pressure.

The rear wall of the receptacle is preterably formed of verticalside-plates 28 having outwardly projected flanges 29 on their inneredges, and central plates 30, having similar flanges 31 on their edges,said flanges being spaced apart to permit the passage of cords or wires,for binding the bale after it is formed. The angle-plate formation alsoserves to add strength to said rear plate.

The shaft 17 is operated by the handwheel 32 to raise the plunger 20,while the shaft is rotated in the opposite direction for compressionpurposes by means of a ratchetwheel 33 on said shaft, and an operatingbar 3-1, the latter devices being of well-known construction. 7

The parts 14, 15, 22, 23, 24c, and 25 are integrally formed, instead ofbeing constructed 01" a supporting plate and devices mounted thereon"for holding the compressing niechanisn'i, as has heretofore been thecase. The unitary construction not only enable this part 01" the machineto be more cheaply produced, as by casting, but it also forms a strongand coinoact frame, well fitted to resist the strain which is placedthereon during the compression operation.

What I claim, and desire to secure is:

1. In a device of the class described, the combination of a receptacleprovided with a hinged closure on one of its sides; a frame formed oftwo iairs of parallel cross-plates united-at their outer ends by platesprovided with wings extending rearwardly between the receptacle Walls,and hingedly connected therewith, a rectangular frame at the inner endsof said cross-plates forming a central vertical guide-way, saidend-plates and guide-way being fitted with transverse shaft, bearings;lips at the forward edge of said first-named frarne projecting be tweenthe side-walls of said receptacle; slotted extensions at the "forwardedge of said first named frame; latches pivoted on said receptacleadapted for engagement with said extensions to hold said first-namedframe in closed position; and compression devices provided with acentral controlling member vertically movable in said guide- Way.

2. in a device of the class described, a supporting frame comprising twopairs oi parallel cross-plates united at their outer ends by slatesprovider with downwardly and outwardly extending wings adapted forpivotal co; iection with the receptacle of a baling machine, and attheir inner ends by a rectangular frame, a pair of lips oroice-teddownwardly from said fir named frame, at the edge thereof opposite tosaid wings, slotted extensions adjacent to said )S, capable of receivingswin 'ing latches, il a guide 7 centrally oi"? said rectangur anie, alloi the parts of said frame icing integrally formed.
